Passing Stack to Function

Question

So I'm playing around with stacks and I've filled one in my main function, but now I want to pass it to my other functions so I can traverse through it. I'm not sure what kind of data type to put into the prototype though so that it accepts it. Suggestions? Here's what I have:

Main.cpp

#include <iostream>
using namespace std;
#include "stack.h"

void displayStack(char &stackRef);

int main()
{
    Stack<char> stack;
    stack.push('a');
    stack.push('b');
    stack.push('c');

    return 0;
};

void displayStack(char starRef)
{
    // Cannot Get here - Errors!
};

It's telling me I have too many arguments and it doesn't match argument list.

Answer 1

This should suffice:

void displayStack(const Stack<char>& stack);
